Happy to approve this one as it's a tiny code change. But I think I'm doing something wrong:

I get a gallery with two images, one of which is a placeholder. It's a good enough experience given one of them isn't valid, but it's not the same results as your described behavior 🤔

[Mamaduka]

@jasmussen, I tested with the .txt file. I think you're getting different results since the .heif is an image type but not supported in WP.

P.S. But behavior from your screencast looks normal to me 👍

[jasmussen]

Thanks for following up.
